CNN's American Morning has a thing for cheesy rock-and-roll intros, and the Daily Show tonight showcased the most embarrassing among them, including Scorpion's "Rock You Like A Hurricane" for a story on Tropical Storm Bertha or "Changes" by David Bowie for everything from credit cards to reform in China.
